Software deployment to multiple computing devices

ABSTRACT

A particular method includes storing a manifest file and a parameters file at a data store. The manifest file and the parameters file are associated with a software deployment package. An application associated with the software deployment package is published to a first remote computing device and to a second remote computing device. The method includes receiving first parameter values from the first remote computing device and receiving second parameter values from the second remote computing device. The first parameter values are stored in a first region of the data store that is specific to the first computing device. The second parameter values are stored in a second region of the data store that is specific to the second computing device.

BACKGROUND

Software developers often make computer programs available via the Internet. For example, instead of installing a local copy of a computer program, a user may access an Internet server (e.g., a target server) that hosts the program. Before a computer program is deployed at a target server and made accessible to others, the computer program may be developed and tested on a local computer. Once the developer is satisfied with the program, the developer may create an installation package that installs the program on the target server. Once the program is installed at the target server, the installation package is discarded.

SUMMARY

Systems and methods of “continuous” publishing of an application are disclosed. A manifest file and a parameters file of a software deployment package may be stored in a central data store. The manifest file may identify components of the application, and the parameters file may identify destination-dependent settings for the application (e.g., settings that vary depending on where the application is installed). The stored files may enable re-creation of the software deployment package and re-publication of the application. For example, when the application is published and installed to a remote computing device (e.g., a target server), a user at the remote computing device may specify device-specific values for the destination-dependent parameters identified by the parameters file. Such device-specific parameter values may be collected from each device where the application is installed and may be stored in the data store on a per-device basis. When a change (e.g., a database update, a database addition, or a bug fix) is detected in the application, the application may be re-published to the remote computing device(s). The re-published application may be configured using the previously stored device-specific parameters, thereby enabling the remote computing device to automatically update the application without re-prompting the user for device-specific configuration information. In addition, if the user modifies the value of any device-specific parameter, the modified value may be transmitted to the data store. Thus, the data store may maintain an updated record of application-specific information (e.g., manifest information and parameters information) and device-specific information (e.g., device-specific parameter values for each computing device where the application is installed).

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.

DETAILED DESCRIPTION

The disclosed techniques may enable “continuous” publication of applications to remote computing devices. For example, manifest and parameters information of an application may be extracted from a software deployment package and may be stored at a centralized data store. The stored manifest and parameters information may enable a computing destination to serve as a publishing source that is capable of re-publishing the application to other publishing destinations. The data store may also include destination-specific parameter values for each publishing destination. For example, users at each publishing destination may provide the destination-specific values when the application is installed for the first time. When the application is subsequently modified, the modification may be propagated to the publishing destinations based on the centrally stored manifest information, the centrally stored parameters information, and the centrally stored destination-specific parameter values without prompting users for destination-specific information.

in a particular embodiment, a computer-implemented method includes storing a manifest file and a parameters file at a record (e.g., a folder) of a data store. The manifest file and the parameters file are associated with a software deployment package at a computing device. The record is specific to an application associated with the software deployment package. The method also includes publishing the application from the computing device to a first remote computing device, receiving first parameter values from the first remote computing device, and storing the first parameter values in the data store. The first parameter values are stored in a first sub-record (e.g., a sub-folder) that is specific to the first computing device. The method further includes publishing the application from the computing device to a second remote computing device, receiving second parameter values from the second remote computing device, and storing the second parameter values in the data store. The second parameter values are stored in a second sub-record that is specific to the second computing device.

In another particular embodiment, a non-transitory computer-readable storage medium includes instructions that, when executed by a computer, cause the computer to receive a software deployment package from a source computing device at a destination computing device. The software deployment package includes a manifest file identifying components of an application. The software deployment package also includes a parameters file identifying one or more destination-dependent parameters of the application. The instructions are also executable by the computer to install the application at the destination computing device and to prompt a user for values of the one or more destination-dependent parameters that are specific to the destination computing device. The instructions are further executable by the computer to transmit the values to a data store for storage.

In another particular embodiment, a computer system includes a processor and a memory that stores instructions executable by the processor to receive a software deployment package. The software deployment package includes a manifest file identifying components of an application. The software deployment package also includes a parameters file identifying one or more destination-dependent parameters of the application. The instructions are also executable to install the application and to store the manifest file and the parameters file at a data store. The instructions are further executable to publish the application to each of a plurality of remote computing devices and to receive parameter values from each of the plurality of remote computing devices. The instructions are executable to store the parameter values received from each particular remote computing device in a region of the data store that is specific to the particular computing device.

FIG. 1 is a diagram of a particular embodiment of a system 100 of publishing an application to multiple computing devices. For example, in the embodiment illustrated, a host computing device 120 may receive a software deployment package 110 associated with a particular application (e.g., web application). The host computing device 120 may publish the application to a plurality of remote computing devices (e.g., a first computing device 130 and a second computing device 140).

In a particular embodiment, the software deployment package 110 is created by a web deploy tool. The web deploy tool may be part of an integrated development environment (IDE). For example, the software deployment package 110 may be associated with an Internet information services (HS) application and may include a manifest file 112 and a parameters file 114 that are represented in extensible markup language (XML). The manifest file 112 may identify components of the web application. For example, the components may include source code files, databases (e.g., database tables, database identifiers, or any combination thereof), and access control lists (ACLs). The manifest file 112 may also include or identify an application provider and a database provider. During installation of the application at a publishing target (e.g., a target server or a target computing device), the application provider may transfer files and data identified by the manifest file 112 to the publishing target. The database provider may create databases identified by the manifest file 112 at the publishing target. An exemplary manifest file is further described with reference to FIG. 3.

The parameters file 114 may identify configuration settings of the application. For example, the parameters file 114 may identify one or more destination-dependent parameters (e.g., services connection strings, database connection strings, application paths, or any combination thereof). The values of such parameters may depend on where the application is installed. To illustrate, the application may make calls to a database when the application is executed. While the application is being developed at a developer's personal computer, the developer's personal computer may store a local instance of the database. Thus, a database connection string of the application under development may point to the local instance of the database (e.g., may refer to “localhost”). When the application is published to an application server, the published application may no longer be able to access the local instance of the database. Thus, the database connection string may be updated to refer to a different instance of the database. In this scenario, the parameters file 114 may identify the database connection string as a destination-dependent parameter. When the application is published, the parameters file 114 may be operable to cause the publishing destination to prompt a user for a destination-specific value for the database connection string. For example, during an installation procedure at a publishing destination, the publishing destination may create and present a user interface based on the parameters file 114, where the user interface may be configured to receive a value for the database connection string. In a particular embodiment, the parameters file 114 also identities a default value for at least one destination-dependent parameter. An exemplary parameters file is further described with reference to FIG. 4.

The host computing device 120 may receive the software deployment package 110 and may install the corresponding application in accordance with the manifest file 112 and the parameters file 114. The host computing device 120 may also store the manifest file 112 and the parameters file 114, or copies thereof, at a data store 121 (e.g., as a manifest file 123 and a parameters file 124). For example, the manifest file 123 and the parameters file 124 may be stored in an application record 122 (e.g., a folder) that is specific to the application. The data store 121 may include application records for any number of applications. Each application record may be specific to a particular application. For example, when application records are represented by folders, the folder for an application may have the same name as the application. In some embodiments, the data store 121 is local to the host computing device, as illustrated in FIG. 1. Alternately, the data store 121 may be remote to the host computing device 120 and accessible via a network (e.g., a local area network (LAN) or the Internet).

The host computing device 120 may publish the application associated with the software deployment package 110 to the remote computing devices 130, 140. For example, initially publishing the application may include transmitting the components of the application identified by the manifest file 112 to the remote computing devices 130, 140. Publishing the application may also include configuring the transmitted application components based on the parameters file 114. For example, users at the remote computing device 130, 140 may be prompted for device-specific parameter values, and the components may be configured based on the device-specific parameter values. The device-specific parameter values may also be transmitted to and stored at the data store 121. For example, the application record 122 may include device-specific sub-records (e.g., sub-folders or data storage regions) 125 and 127 for each of the remote computing devices 130 and 140, respectively. To illustrate, the sub-folder specific to a computing device may be named using a domain name service (DNS) name. Internet protocol (IP) address, media access control (MAC) address, or other identifier of the computing device. Each sub-folder may include device-specific parameter values for a corresponding remote computing device (e.g., illustrative first parameter values 126 and second parameter values 128 for the remote computing devices 130 and 140, respectively). In a particular embodiment, the first parameter values 126 and the second parameter values 128 are represented in XML. Moreover, the first parameter values 126 and the second parameter values 128 may be encrypted. Exemplary parameter values are further described with reference to FIG. 5.

In a particular embodiment, the host computing device 120 is operable to detect a change in the application. For example, the change may include an update to a database used by the application or the addition of a new database. The change may also include source code modifications or data modifications associated with a hug fix or with a software update. In response to the change, the host computing device 120 may automatically update the stored manifest file 123, the stored parameters file 124, or any combination thereof. For example, the host computing device 120 may add an identifier for a new database to the manifest file 123 and may add destination-dependent parameters of the new database to the parameters file 124.

The host computing device 120 may also re-publish the application to propagate the detected change to publishing destinations (e.g., the remote computing devices 130, 140). In a particular embodiment, re-publishing an application to a publishing destination includes transmitting all application files and data to the publication destination. Alternately, re-publishing the application may include transmitting only those files that have changed since the previous publication. In addition, when an application is re-published, the application components (e.g., as defined by the stored manifest file 123) may be pre-configured based on stored parameter values. To illustrate, the application mg be re-published to the first remote computing device 130 based on the stored first parameter values 126 and re-published to the second remote computing device 140 based on the stored second parameter values 128. It will be appreciated that since re-published application components may be pre-configured for individual publishing destinations, applications may be re-published without repeatedly prompting users for device-specific configuration information.

In a particular embodiment, the data store 121 is accessible via an application programming interface (API). For example, the host computing device 120 may store and retrieve information to and from one or more of the manifest file 123, the parameters file 124, the first parameter values 126, and the second parameter values 128 via the API or via a different API. The remote computing devices 130, 140 may also communicate with the data store 121 via the API.

During operation, the host computing device 120 may receive the software deployment package 110 from a publishing source (not shown). For example, the software deployment package 110 may include the manifest file 112 and the parameters file 114, which may describe how to install and configure a web application at the host computing device 120. The host computing device 120 may install the web application based on the manifest file 112 and the parameters file 114. The host computing device 120 may also save manifest information and parameters information at the data store 121 (e.g., as the manifest file 123 and the parameters file 124). The host computing device 120 may then serve as a publishing source with respect to the remote computing devices 130, 140. For example, the host computing device 120 may publish the web application to the remote computing devices 130, 140. Each of the remote computing devices 130, 140 may transmit values for destination-dependent parameters of the web application that are stored at the data store 121. When the web application is updated, the host computing device 120 may re-publish the web application to the remote computing devices 130, 140.

It will be appreciated that the system 100 of FIG. 1 may enable continuous publication of applications. For example, a computing device (e.g., the host computing device 120) may serve as a publication destination, a publication source, or both. In addition, the system 100 of FIG. 1 may provide centralized storage of publishing data such as manifest information, parameters information, and device-specific configuration information. At any point in time, the central data store (e.g., the data store 121) may access the application-specific information (e.g., the manifest file 123 and the parameters file 124) and the device-specific information (e.g., the first parameter values 126 and the second parameter values 128) tore-publish the application. The system 100 of FIG. 1 may thus enable automated publication and re-publication of applications with reduced user intervention.

FIG. 2 is a diagram of another particular embodiment of a system 200 of publishing an application to multiple computing devices. The particular embodiment of FIG. 2 is described with reference to a software development enterprise. It should be noted, however, that the systems and methods disclosed herein may apply to any type of enterprise or business workflow.

As depicted in FIG. 2, a developer workstation 210 may publish an application (e.g., a web application) to a shared development server 220. For example, the developer workstation 210 may be associated with a software developer that builds an application. When the developer is satisfied with the application, the developer may publish the application to the shared development server 220. For example, the shared development server 220 may be a team server that is available to members of a software development team to publish “alpha” and “beta” web applications for testing. In a particular embodiment, the shared development server 220 receives a software deployment package from the developer workstation 210. For example, the software deployment package may be similar to the software deployment package 110 of FIG. 1 and may include a manifest file and a parameters file similar to the manifest file 112 and the parameters file 114 of FIG. 1. The shared development server 220 may install the application and may prompt a user for parameter values that are specific to the shared development server 220. The developer workstation 210 may receive the device-specific parameter values from the shared development server 220 and may store the device-specific parameter values at a data store 212.

The application may be re-published from the developer workstation 210 to the shared development server 220 as the software developer tests and updates the application. In a particular embodiment, the shared development server 220 may receive a second (e.g., updated) software deployment package from the developer workstation 210. The second software deployment package may include or may have been pre-configured using the previously stored device-specific parameter values from the data store 212. The shared development server 220 may automatically update the application based on the second software deployment package without prompting the user regarding the destination-dependent parameters.

When the application is ready for production (e.g., ready to be released to the public), the application may be published to one or more web servers (e.g., including an illustrative web server 230). In a particular embodiment, the software developer uses the developer workstation 210 to publish the application to the web server 230. Device-specific parameter values for the web server 230 may be stored at the data store 212. Alternately, the application may be published to the web server 230 from the shared development server 220, and device-specific parameter values for the web server 230 may be stored at a data store 222 of the shared development server 220. In other embodiments, the data stores 212, 222 may be at other locations, may be combined into a single data store, or any combination thereof.

FIG. 3 is a diagram to illustrate a particular embodiment of a manifest file 300 represented in XML. In an illustrative embodiment, the manifest file 300 may be the manifest file 112 or the manifest file 123 of FIG. 1.

In a particular embodiment, published applications are represented by a computer directory structure. For example, as illustrated in FIG. 3, a root folder “MyApp” of an Internet information services (IIS) application may serve as an IIS application path. The root directory may include one or more sub-folders that include components of the application. For example, as illustrated in FIG. 3, the “MyApp” root folder may include an “App_pata” sub-folder to store application data, a “Media” sub-folder to store media, a “Modules” sub-folder to store modules, and a “Themes” sub-folder to store themes.

The manifest file 300 may also include security or access control list information for the application. For example, as illustrated in HG, 3, each sub-folder may be associated with a “Modify” permission. Alternately, one or more of the sub-folders may have other permission values (e.g., “Read-only”). The manifest file 300 may further include or identify a database provider. For example, as illustrated in FIG. 3, an “install.sql” script may be executable at publishing destinations to create and update databases or database connections that may be used by the application.

FIG. 4 is a diagram to illustrate a particular embodiment of a parameters file 400 represented in XML. In an illustrative embodiment, the parameters file 400 may be the parameters file 114 or the parameters file 124 of FIG. 1.

The illustrated parameters file 400 FIG. 4 includes information for eight destination-dependent parameters having the names “Application Path,” “SetAclParameter,” “Database Server,” “Database Name,” “Database Username,” “Database Password,” “Settings Data Provider for SQL,” and “Settings Data Connection String for SQL.” It should be noted that information associated with any number of destination-dependent parameters may be included in a parameters file. The parameters file 400 may also include one or more of a description, a default value, and tag(s) for each destination-dependent parameter. For example, the “Application Path” parameter may have a description “Full site path where you, would like to install your application (i.e. Default Web Site/MyApp),” a default value “Default Web Site/MyApp,” and a tag “iisapp.” in a particular embodiment, the name, the description, the default value, and/or the tags) of a parameter are used to construct a user interface that includes a prompt to accept the default value or to provide a different device-specific value for the parameter.

FIG. 5 is a diagram to illustrate a particular embodiment of destination-specific parameter values 500 corresponding to the parameters file 400 of FIG. 4.

For example, as illustrated in FIG. 5, the application path parameter may have a value “Default Web Site/wordwrite,” the database server parameter may have a value “localhost,” (e.g., indicating that the publication destination in question has a local copy of the database), the database name parameter may have a value “wordwrite,” the database user name parameter may have a value “wordwriteuser,” and the database password parameter may have a value “mydbpassword.”

The parameter values 500 may also include one or more encrypted values. In a particular embodiment, the encrypted values are represented as key-value pairs. For example, the illustrated parameter values 500 include four encrypted values having keys “Key1,” “Key2,” “Key3,” and “Key4.” The parameter values 500 may also include a package globally unique identifier (GUID). The package GUID may identify the software deployment package whose installation resulted in the parameter values 500.

FIG. 6 is a flow diagram to illustrate a particular embodiment of a method 600 of publishing an application to multiple computing devices. In an illustrative embodiment, the method 600 may be performed at the system 100 of FIG. 1 or the system 200 of FIG. 2.

The method 600 may include receiving, at a destination computing device, a software deployment package associated with an application from a source computing device, at 602. The software deployment package may include a manifest file and a parameters file. For example, in FIG. 1, the host computing device 120 may receive the software deployment package 110, which includes the manifest file 112 and the parameters file 114.

The method 600 may also include installing the application at the destination computing device, at 604, and storing the manifest file and the parameters file at a data store, at 606. The data store may be a local data store or a remote data store. For example, in FIG. 1, the host computing device 120 may install the application and may store the manifest file 123 and the parameters file 124 at the data store 121.

The method 600 may further include publishing the application to each of a plurality of remote computing devices, at 608, and receiving destination-specific parameter values from each of the plurality of remote computing devices, at 610. For example, in FIG. 1, the host computing device 120 may publish the application to the remote computing devices 130 and 140. The host computing device 120 may receive the first parameter values 126 from the first remote computing device 130 and the second parameter values 128 from the second remote computing device 140.

The method 600 may include storing the destination-specific parameter valves received from each remote computing device in a region of the data store that is specific to the remote computing device, at 612. For example, in FIG. 1, the first parameter values 126 may be stored in the first sub-record 125 and the second parameter values 128 may be stored in the second sub-record 127.

The method 600 may also include detecting a change in the application, at 614, and updating one or more of the manifest file and the parameters file in response to the change, at 616. For example, in FIG. 1, the host computing device 120 may update one or more of the manifest file 123 and the parameters file 124 in response to the change.

The method 600 may further include re-publishing the application to each remote computing device based on the stored destination-specific parameter values corresponding to the remote computing device, at 618. For example, in FIG. 1, the host computing device 120 may re-publish the application to the remote computing devices 130, 140. Application components transmitted to the first remote computing device 130 may include or may be pre-configured based on the first parameter values 126. Application components that are transmitted to the second remote computing device 140 may include or may be pre-configured based on the second parameter values 128. For example, a database connection string for the first remote computing device 130 may be pre-configured to point to a local database instance at the first computing device, and a database connection string for the second remote computing device 140 may be pre-configured to point to a remote database instance accessible via the Internet.

FIG. 7 shows a block diagram of a computing environment 700 including a computing device 710 operable to support embodiments of computer-implemented methods, computer program products, and system components according to the present disclosure. For example, the computing device 710 or components thereof may include, implement, or be included as a component of the system 100 of FIG. 1 or the system 200 of FIG. 2.

The computing device 710 includes at least one processor 720 and a system memory 730. For example, the computing device 710 may be a desktop computer, a laptop computer, a tablet computer, a mobile phone, a server, or any other fixed or mobile computing device. Depending on the configuration and type of computing device, the system memory 730 may be volatile (such as random access memory or “RAM”), non-volatile (such as read-only memory or “ROM,” flash memory, and similar memory devices that maintain stored data even when power is not provided), non-transitory, or some other memory. The system memory 730 may include an operating system 732, one or more application platforms 734, one or more applications, and program data 738.

The computing device 710 may also have additional features or functionality. For example, the computing device 710 may also include removable and/or non-removable additional data storage devices, such as magnetic disks, optical disks, tape, and memory cards. Such additional storage is illustrated in FIG. 7 by removable storage 740 and non-removable storage 750. Computer storage media may include volatile and/or non-volatile storage and removable and/or non-removable media implemented in any technology for storage of information, such as computer-readable instructions, data structures, program components, or other data. The system memory 730, the removable storage 740, and the non-removable storage 750 are each examples of computer storage media. The computer storage media includes, but is not limited to, RAM, ROM, electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technology, compact disks (CD), digital versatile disks (DVD) or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to store information and that can be accessed by the computing device 710. Any such computer storage media may be part of the computing device 710. In a particular embodiment, the computing device 710 also includes a data store 702. For example, the data store may be the data store 121 of FIG. 1, the data store 212 of FIG. 2, or the data store 222 of FIG. 2. The data store 702 may be implemented as a separate storage device or as part of the removable storage 740, the non-removable storage 750, or both.

The computing device 710 may also have input device(s) 760, such as a keyboard, mouse, pen, voice input device, touch input device, etc. connected via one or more input interfaces. Output device(s) 770, such as a display, speakers, printer, etc. may also be included and connected via one or more output interfaces.

The computing device 710 also contains one or more communication connections 780 that allow the computing device 710 to communicate with other computing devices over a wired or a wireless network. For example, the one or more communication connections 780 may represent an interface that communicates with the other computing devices via a network. In a particular embodiment, the communication connections 780 enable the computing device 710 to communicate with one or more application sources (e.g., an illustrative application source 704) and one or more publication destinations (e.g., illustrative publication destinations 706, 708). In a particular embodiment, the data store 702 is external to the computing device 710 and is accessible via the communication connections 780.

It will be appreciated that not all of the components or devices illustrated in FIG. 7 or otherwise described in the previous paragraphs are necessary to support embodiments as herein described. For example, the removable storage 740 may be optional.

 3. The method of claim 2, wherein the change in the application comprises an update to a database or an addition of a new database.
 4. The method of claim 2, further comprising: re-publishing the application to the first remote computing device based on the stored first parameter values; and re-publishing the application to the second remote computing device based on the stored second parameter values.
 5. The method of claim 1, further comprising: receiving the software deployment package from an application source; and installing the application at the computing device.
 6. The method of claim 1, wherein the data store is located at the computing device.
 7. The method of claim 1, wherein the data store is remote to the computing device.
 8. The method of claim 1, wherein the data store is accessible by the first remote computing device and the second remote computing device via an application programming interface (API).
 9. The method of claim 1, wherein the manifest file identifies one or more components of the application and wherein the parameters file identifies one or more destination-dependent parameters of the application.
 10. The method of claim 9, wherein the one or more components include one or more source code files associated with the application, one or more database identifiers of one or more databases associated with the application, one or more access control lists (ACLs) associated with the application, an application provider to transfer application files to a publishing destination, a database provider to transfer database content to the publishing destination, or any combination thereof.
 11. The method of claim 9, wherein the parameters file identifies a default value for at least one destination-dependent parameter.
 12. The method of claim 9, wherein the parameters file is operable to cause a publishing destination to prompt a user for destination-specific values of destination-dependent parameters and to transmit the destination-specific values to the data store.
 13. The method of claim 10, wherein publishing the application to a particular remote computing device comprises: transmitting the components of the application identified by the manifest file to the particular remote computing device; and configuring the transmitted components of the application based on one or more of the parameters file and stored parameter values at the data store that are specific to the particular remote computing device.
 14. The method of claim 1, wherein the manifest file and the parameters file are each represented in extensible markup language (XML).
 15. The method of claim 1, wherein the application comprises an Internet information services (IIS) web application.
 16. A non-transitory computer-readable storage medium comprising instructions that, when executed by a computer, cause the computer to: receive a software deployment package from a source computing device at a destination computing device, wherein the software deployment package includes a manifest file identifying components of an application, and wherein the software deployment package includes a parameters file identifying one or more destination-dependent parameters of the application; install the application at the destination computing device; prompt a user for values of the one or more destination-dependent parameters that are specific to the destination computing device; and transmit the values to a data store for storage.
 17. The non-transitory computer-readable storage medium of claim 16, further comprising instructions that, when executed by the computer, cause the computer to: receive a second software deployment package associated with the application from the source computing device, wherein the second software deployment package includes the stored values of the one or more destination-dependent parameters; and update the application at the destination computing device based on the second software deployment package without prompting the user regarding the one or more destination-dependent parameters.
 18. A computer system, comprising a processor; and a memory storing instructions executable by the processor to: receive a software deployment package, wherein the software deployment package includes a manifest file identifying components of an application, and wherein the software deployment package includes a parameters file identifying one or more destination-dependent parameters of the application; install the application; store the manifest file and the parameters file at a data store; publish the application to each of a plurality of remote computing devices; receive parameter values from each of the plurality of remote computing devices; and store parameter values received from each particular remote computing device in a region of the data store that is specific to the particular computing device.
 19. The computer system of claim 18, wherein the one or more destination-dependent parameters include a services connection string, a database connection string, an application path, or any combination thereof.
